SHOEMTREEING MACHINE.

SPECIFICATION forming part of Letters Patent No. 622,643, dated April 4,1899-.

Application filed September 2, 1897. serial No. 650,408- (No model.)

To all whom it may concern.-

Be it known that I, ABEL D. TYLER, J r., of Brockton, in the county ofPlymouth and State of Massachusetts, have invented a new and ImprovedShoe Treeing Machine, of which the following is a specification.

Referring to the accompanying drawings, Figure 1 is a side elevation ofmy improved last-supporting device, showing the internal parts in dottedlines and the levers and treadles for operating the same. Fig. 2represents a top View of my last-arm with a last attached thereto. Fig.3 is asectional elevation through line 3 3 in Fig. 2. Fig. 4 is across-section through line 44in Fig. 3. Fig. 5 is a cross-sectionthrough line 5 5 in Fig. 3.

In the drawings illustrating the principle of myinvention and the bestmode now known to me of applying that principle, A is the lastarmsupport, which may be of the form shown or any other suitable form. B isthe last-arm, D the last, here shown as a transversely-divided andhinged last, although it may be the ordinary block-last, if so desired,so far as the broader embodiment of my invention is concerned, and E isa lever which connects the clamping mechanism, hereinafter described,with the treadle-rod F and t'readle F.

The last-arm supportA is formed with a suitable bearing afor the journalendb of the lastarm 13, but may be otherwise of any suitable form orconstruction. Last-arm B is formed with a longitudinally-extendingchamber 1), at the rear of which is the journal end I), and in front ofwhich, in the solid fiat end portion 5 is the spindle-recess 19 whichopens on the front end wall of the arm and leads back into chamber 1).The front end of the arm is preferably fiat and beveled upwardly andoutwardly from the heel side toward the toe side, so as to keep the toeof the last tipped outwardly, so that the operator may work on the vampwith greater convenience and 00111- fort, and is provided with anoutwardly-proend of which projects from the rear end of p the last-arm.To the rod B there is connect= ed a slide-bar B conveniently formed withside dovetails U, which run in the lengthwise extending dovetail groovesa within chamber b. The connection of rod B and slide-bar 13 1sconveniently made by forming the bar 13 with an ear b having an orificethrough which the rod B freely passes, a coiled spring 12' being mountedbetween the outer end of ear I) and an abutment 6 fast on the inner endportion of the rod. A coiled spring 19 is also mounted between ear I)and the rear end wall of chamber 1). Rod B is a sliding fit in theorifice in the car, as well as in its bearing in the journal end 17. Thefront portion of the slide-bar is provided with a boss 11 upon whichrests the tail 6 of the pivoted clutch B, the front end of which isformed with a hook 12 and is in line with the spindle-recess Z7 Last Dis preferably a transversely-divided and hinged last comprising thequarters-block d (or heel-piece) and the vamp-block d (or fore part) anda suitable hinge d whereby the quarters-block and vamp-block are hingedtogether, and the last is shortened when the Vamp-block is tippedforward and the removal of the shoe from the last greatly facilitated.

In the quarters-block at there is rigidly secured a spindle D,projecting outwardly from the top thereof. The foot of spindle D isinserted some distance into the quarters-block and there secured by atransverse fastener or rivet d so that the spindle and quarterspiece arerigidly connected. Spindle D is provided with a notch d with which thehook 11 engages when the last is secured on the last-arm. In the upperwall of the quartersblock there is also provided a recess d to re ceivethe steady-pin b the top of the quarters-block being preferably flat tofit smoothly and snugly against the preferably flat outer end of thelast-arm. Journal end I) of the last-arm is preferably formed with acircumferential groove 1) within the bearing a, and a screw a isprovided to turn through bearing a to engage with the bottom of thegroove 12 When journal end I) of last-arm B is in place in its bearinga, the shoulder 11 of the arm is against the inner side of the bearing aand the arm restrained from back motion when the reciprocating rod B ispulled outwardly. Last-arm B, as shown, is rotatively mounted in thebearing a, though a rocking movement would suffice. The cooperatinggroove Z7 and screw form a convenient means for preventing the last-armB from being pulled forwardly in the bearing a. To mount the last on thelast-arm, spindle D is inserted in spindle-recess b the steady-pin bthen entering the recess (1 in the quartersblock and the top of thequarters-block bearing against the outer end of the last-arm. When thisinsertion is made, slide-bar B is in such a forward position that theclutch B is free. By moving the rod B outwardly the slide-bar B is drawntoward and under the tail of clutch B and the boss 12 then pushing thetail 0 of the clutch outwardly and moving the hook 12 of the clutch intoengage= ment with the notch on the spindle and drawing the top of thequarters-block tight against the opposed end of the last-arm.

When the shoe is on the last, (and it is frequently made on the last,)the operator pushes or pulls the last, thereby rocking or rotating thelast-arm and getting all parts of the vamp and quarters into convenientposition for rubbing and smoothing or other desired treatment.

To move rod B rearwardly to lock the spindle in the last-arm, a greatvariety of devices may be used; but I hereby show a treadle mechanismalready described. A spring f is desirably employed to return the leverE, and a serrated vertical plate f is shown for confining the treadle ina depressed position, the edge of plate f on the treadle engaging with atooth or plate f to hold the treadle down. When the treadle is released,the springs 17 and b expand and throw boss b forwardly out of engagementwith the tail of the clutch, and the tail of the clutch then falls bygravity or the front end of it is lifted by the expansion of the springI) to throw the clutch out of engagement with the spindle. By this construction lasts with the shoes on themmay be rapidly put on andtaken'off the machine. 7

It is sometimes desirable to put on or take off shoes from the lastsafter they are locked -on the last-arm, and while an ordinary blocklastmay be used, if desired, a transverselydivided hinged last is highlyadvantageous,

as it greatly increases the speed of the operator in making the changes.As the heel part or quarters-block is rigidly clamped to the.

last-arm, a pull on the heel portion of the shoe will tend to'tip thefore part over the,

last-arm, and thereby shorten the last, so that the shoe may be takenoff easily and without distorting the shoe.

The machine shown and thus far described is especially adapted for usein treating the leather on the last, and it is desirable in theseoperations that the last-arm should be horizontal; but features of myinvention are capable of embodiment in various other forms .and inmachines adapted for presenting sole ing last-arm may be detachablyclamped in many ways other than that shown without departure from myinvention. The springs b and 17 give a resiliency to the action of theconnected rod B and slide-bar B that is more desirable than a rigidconnection between the two parts, and the use of the clutch-returningspring 11 is highly desirable, as the clutch is thereby lifted instantlythe treadle is released whatever the position of the-last-arm on thelengthwise axis. As the boss 79 is drawn rearwardly against the underside of the tail b of the pivoted clutch the latter draws the spindle Dinwardly, tightly looking the last in place on the last-arm. As shown inthe drawings, the slide-bar B and rod B are at their extreme rearwardposi* tions and springs 19 and b are compressed. The rod B rotatesfreely in the cross-piece Z2 and the loop I), to which the lever E (orother power) is applied. A cover b is con Venient for the opening intochamber Z2.

\Vhat I claim is- 1. The combination with a last-arm and atransversely-divided, hinged last;the arm and heel part of the lastbeing provided with (3061)- crating locking members, of means forlooking and unlocking said members, the fore part of the last being freefor tilting.
